[jdom-interest] Adding String to Element where String contains an Element in String form

Tue May 28 14:57:49 PDT 2002

I am trying to use xml in the generation of a jsp.

In jsp you can use custom tags to retrieve dynamic
content.  For example:

---start jsp-----

<%@ taglib uri="/WEB-INF/tld/mycustomtaglib.tld"
prefix="javacustomtag" %>

<html>
Hello <javacustomtag:GetName/>, how are you today
</html>

---end jsp-----

when this is loaded by the appserver/webserver and
displayed to the user the javacustomtag is executed
like
a normal java call and using the id stored in the http
session it retrieve the user's real name from the db
so the user would see upon source view

---- start html ----

<html>
Hello John Smith, how are you today
</html>

---- end html ----

Now if I define my namespace javacustomtag then the
custom tag is output by the XMLOutputter class as 

<javacustomtag:GetName xmlns:help="ignore"/>

which isn't identified by the jsp processor as a valid
custom tag and subsequently the html the user sees is:

---- start html ----

<html>
Hello <javacustomtag:GetName xmlns:help="ignore"/>,
how are you today
</html>

---- end html ----

I hope that clears things up.
